What is an Ignition Coil Pack?

An ignition coil pack is a component of an engine that helps to start the engine. It consists of several coils, each of which is connected to the spark plugs. When the engine is started, these coils heat up and create sparks that ignite the fuel in the cylinders.

How to Test an Ignition Coil Pack

There are a few ways to test an ignition coil pack. One way is to use an ohmmeter to check for continuity between the coils and the connector. If there is no continuity, the coil pack may need to be replaced. Another way is to use a voltmeter to measure voltage at different points on the coil pack. If there is a problem with the coil pack, the voltage will be low at certain points.

What to do if the Test Results Are Negative

If the test results are negative, you can continue to drive the engine, but keep an eye out for any warning lights or symptoms that may indicate a problem. If you notice anything abnormal, take your car in for service right away.
